Played it and rated it. My comment on the jam page got stuck behind a CAPTCHA, so here it is. Played level 1 on Normal over a few runs. The DOS boot ("Loading him ...... OK") and the title shot of him standing at the end of the corridor set the mood before you even start, and the pixel brick-and-blood walls look great. I found all three pieces and forged the key. The forge taking a few seconds while you stand there exposed is a great tension spike: he showed up mid-forge and took a heart. I got the door open once, and the lock waking him is a nasty twist. He caught me before I reached the exit. "Look at him and he freezes" reads clearly, and the pause-screen hints help. Full disclosure: I can't hear the audio, and I steered with a script that reads the maze and presses the keys, so I can't fairly judge how hard it is to find your way by eye.
